Aim.The introduction of the full paper reviews a number of papers in the open literature and then proposes what we believe to be a better algorithm, which has a microcosmic discrete evacuation model based on CA and which is explained in sections 1, 2 and 3.The core of section 2 is that it discusses individual passenger' s knowledge of the airplane, his realization of the emergency development, and the repulsive influence between passengers.The core of section 3 consists of: ( 1 ) each passenger' s orientation choice; (2) each passenger' s velocity calculation; (3) lastly but most importantly “information spread” update strategy, which is very much different from past ones.Finally, for comparing the proposed algorithm with traditional CA models, we give a numerical simulation example.The results, presented in Table 2 and Fig.9, demonstrate preliminarily that the effectiveness and accuracy of our algorithm as applied to airplane are better than those of traditional CA models.%提出采用基于信息流传播更新机制的元胞自动机算法进行客机应急撤离问题的求解.算法利用带缩放系数的微观离散网格描述客机客舱布置方案,考虑了旅客不同属性对撤离过程的动态影响,采用信息流更新机制对撤离过程进行模拟,有效地解决了采用传统并行更新机制模拟与实际撤离过程不一致的问题.实例仿真结果表明,文中的算法与传统元胞自动机算法相比,更接近于试验结果.
